Teeth cleaning animal chew

ABSTRACT

A composition of matter for dental plaque removal comprising at least one of a strain of the bacteria  Bacillus licheniformis  and the extracellular enzymes produced by  B. licheniformis,  and at least one of a natural and synthetic polymer, are disclosed. A method of manufacturing an animal chew or food item coated with the disclosed composition of matter, and animal chews or food items produced therefrom, are also disclosed.

BACKGROUND

Ascophyllum nodosum is a type of algae, commonly known as Norwegian kelp or seaweed. It is known to have many health benefits. The proteins, peptides, amino acids, fatty acids, polysaccharides, vitamins, minerals and anti-oxidants contained in kelp work in synergy with each other, and are believed to have anti-cancer, anti-inflammatory, anti-coagulant and hypocholesterolemic activities. Additionally, the high content of vitamins, minerals, and iodine provide added nutritional value. A variety of products for animals to chew, or gnaw on, incorporate A. nodosum for its nutritional and health benefits. The chewing or gnawing action provides a mechanical means to help remove dental plaque.

SUMMARY

The present disclosure has applications in the dental health sector. The embodiment of the present invention is an animal chew comprising: a first coating that removes dental plaque located on at least a portion of a surface of the animal chew wherein the first coating is a composition that comprises a strain of Bacillus licheniformis obtained from Norwegian kelp, an extracellular enzyme produced by the Bacillus licheniformis, and at least one of a natural polymer and a synthetic polymer; a second coating located on the portion of the surface of the animal chew, wherein the second coating comprises collagen, gelatin, glycerin, or a combination thereof.

In addition to the exemplary aspects and embodiment described above, further aspects and embodiments will become apparent by study of the following descriptions.

BRIEF DESCRIPTION OF THE FIGURES

The accompanying figures, which are incorporated herein and form a part of the specification, illustrate some, but not the only or exclusive, example embodiments and/or features. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than limiting.

FIG. 1 shows a flow diagram for a method of coating an animal chew with a composition comprising extracellular enzymes produced by B. licheniformis.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiments include methods and compositions to aid in the removal of dental plaque from animals comprising applying a composition of the bacteria Bacillus licheniformis, and/or the extracellular enzymes produced by B. licheniformis to an animal chew. The composition may further comprise natural and/or synthetic polymers or mixtures of compounds and additional bacteria, for example, strains of Lactobacillus.

Bacillus licheniformis

B. licheniformis is an endospore forming bacteria commonly found in the soil and on bird feathers, and most recently on the seaweed A. nodosum, and can also be obtained from a microbial depository, for example, the American Tissue Culture Collection (ATCC) or it may also be commercially purchased, for example, from BIO-CAT Microbials. Specific enzymes produced by B. licheniformis may also be commercially purchased, for example, from Merck Millipore or Sigma-Aldrich.

Dental Plaque

Plaque is a sticky film, more specifically a biofilm. Biofilms are aggregations of microorganisms that secrete adhesive mucilage, also known as a glycocalyx, thereby gluing themselves to surfaces. While some biofilms are beneficial, dental plaque is a type of harmful biofilm. The acids produced by the bacteria of dental plaque damage tooth enamel and surrounding gums, and can lead to tooth decay, gingivitis, and periodontitis

Recent studies suggest that strains of the bacteria Bacillus licheniformis found on A. nodosum produce extracellular enzymes, such as various proteases and lipases. B. licheniformis also release a nuclease which is capable of hydrolyzing the phosphodiester backbone of DNA. It is hypothesized that these enzymes break up the biofilm and release the bacteria, thus helping to break down oral plaque and reducing dental carries.

Enzymes

With the exception of a few catalytic RNA molecules, enzymes are proteins. Enzymes catalyze specific metabolic reactions, either to build new molecules (anabolic reactions), or break them down into simpler products (catabolic reactions). There are many different types and classes of enzymes. For example, hydrolases are a group of approximately 200 enzymes that use water to break bonds within compounds, separating them into simpler products. Included in the hydrolase group are, for example, esterases, which include lipases, phosphatases, which include nucleases, glycosidases, which include carboydrases and amylases, and peptidases (also known as proteinases or proteases). Other classes of enzymes include isomerases, ligases, lyases, oxidoreductases, and transferases.

Enzyme Production from B. licheniformis

To prepare the composition of the present disclosure, B. licheniformis may be cultured and induced to produce enzymes by any number of means known in the art. B. licheniformis is a Gram-positive endospore forming organism that can be isolated from soils and plant material all over the world, Additionally, various strains can be obtained from a number of microbial depositories. This organism is used extensively for large-scale industrial production of exoenzymes as it can secrete large quantities of proteins of up to 20-25 g/l (Divakaran D, Chandran A, Pratap Chandran R. Comparative study on production of α-Amylase from Bacillus licheniformis strains, Brazilian Journal of Microbiology. 2011; 42(4):1397-1404).

A. Alkaline Proteases

For example, as reported by Sarker et al., to produce alkaline proteases from B. licheniformis, a media containing glucose, peptone, K₂HPO₄, MgSO₄ and Na₂CO₃ at pH 10 was used. Maximum level of enzyme production was obtained after 48 h of incubation with 2% inoculum size at 42° C., under continuous agitation at 150 rpm, in growth medium of pH 9. Highest enzyme production was obtained using 1% rice flour as carbon source and 0.8% beef extract as organic nitrogen source. This particular enzyme is suitable for industrial applications such as in the detergent, food, pharmaceutical, and leather industries (see for example, Sarker P K, Talukdar S A, Deb P, Sayern S A, Mohsina K. Optimization and partial characterization of culture conditions for the production of alkaline protease from Bacillus licheniformis P003. SpringerPlus. 2013; 2:506). See also U.S. Pat. No. 4,559,307, incorporated herein by reference for all that it discloses and teaches.

B. Alpha Amylase

To produce α-amylase, an extracellular enzyme that breaks down starch into the disaccharide maltose, Divakaran et al., used two strains of Bacillus licheniformis, MTCC 2617 and 2618, and four different substrates, starch, rice, wheat and ragi powder, as a carbon source by submerged fermentation. After culture and centrifugation, the supernatant was purified to obtain crude enzyme, which was further purified by ammonium sulfate precipitation, dialysis and ion-exchange chromatography to obtain pure enzyme. Amylase has extensive application in food, starch liquefaction, saccharification, detergent, brewing, paper, textile and distilling industries (see for example, Divakaran D, Chandran A, Pratap Chandran R. Comparative study on production of α-Amylase from Bacillus licheniformis strains, Brazilian Journal of Microbiology, 2011; 42(4):1397-1404).

C. Keratinase

Lin et al. isolated a keratinase from the culture medium of feather-degrading Bacillus licheniformis PWD-1 by use of an assay of the hydrolysis of azokeratin. Membrane ultrafiltration and carboxymethyl cellulose ion-exchange and SEPHADEX G-75 gel chromatographies were used to purify the enzyme (see for example, Xiang Lin, Chung-Ginn Lee, Ellen S. Casale, Jason C. H. Shih, Appl. Environ. Microbiol. October 1992 vol. 58 no. 10 pg 3271-3275). See also U.S. Pat. No. 5,171,682, incorporated herein by reference for all that it discloses and teaches.

E. Mannanase

Zhang et al. reported a technique for purifying β-mannanase from B. licheniformis using flocculation, ultrafiltration, and ion-exchange chromatography. Mannanses are useful in the food and feed processing industries, pulp and paper industries, and the stimulation of oil and gas well (see for example, Zhang, J, He, Z. and Hu K.

Example 1—A Method of Coating an Animal Chew with a composition Comprising Extracellular Enzymes Produced by B. licheniformis

B. licheniformis is commonly found in, and can be obtained from, the soil, on bird feathers, and most recently on the seaweed A. nodosum. B. licheniformis can also be obtained from any number of microbial depositories and commercially purchased. As shown in the flow diagram of FIG. 1, B. licheniformis is cultured (101) and then induced to produce a desired enzyme (103). A number of culturing techniques for the production of enzymes are well known in the art. See for example, Divakaran D, Chandran A, Pratap Chandran R. Comparative study on production of α-Amylase from Bacillus licheniformis strains. Brazilian Journal of Microbiology. 2011; 42(4):1397-1404, Sarker P K, Talukdar S A, Deb P, Sayem S A, Mohsina K. Optimization and partial characterization of culture conditions for the production of alkaline protease from Bacillus licheniformis P003. SpringerPlus. 2013; 2:506, Xiang Lin, Chung-Ginn Lee, Ellen S. Casale, Jason C. H. Shih, Appl. Environ. Microbiol. October 1992 vol. 58 no. 10 pg 3271-3275, and Zhang, J, He, Z. and Hu K. Biotechnology Letters, 2000 vol. 22 pg 1375-1378.

Following culture and enzyme production, the enzymes are extracted and purified (105). A number of enzyme extraction and purification methods are well known in the art.
